1M PARovEM ENT A|N-SHU''Tl-:R-FASTENINGSL Specification forming part of Letters Patent No. 197,390, dated November 20, 1877; application filed September 12, 1877.

To all whom it may concern: A

Beit known that I, ELDRIDGE Mix, of Orange, in the county, of Essex and State of New Jersey, have invented a new and useful Improvement in Blind-Fastenings, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to that description of fastenings for the outside blinds or shutters of windows in which a spring double hook for holding said blinds open or closed is used, and in which said hook has combined with it a bar or attachment for manipulating or releasing the hook when the lower one of a pair of window-sashes is raised, and for locking or holding the blind when hooked and closed by the shutting down of the lower sash.

The invention consists in a certain construction of the hook manipulating and locking bar, whereby said bar is made capable of engaging not only with a stationary pin or staple in the window frame or sill, but also with the lower sash itself when the latter is closed,

thus not depending exclusively upon the pin or staple, which is apt to be bent or work loose, and other advantages are obtained.

The invention also consists in a combination, with the spring double-hook blind-fastening and attached locking-bar, of a flexible clamp for uniting said bar with said hook, whereby said bar may be readily applied to hook-fastenings for outside blinds and shuttersnow in use. Figure 1 is a sectional perspective view of a lower window-sash, window-frame, and a blind in part, with my invention applied, and showing said sash as locking the blind when closed. Fig. 2 is a vertical section, upon a larger scale, of the samein part, but showing the locking-bar as engaging with a staple to hold the blind closed when the sash is raised; and Fig. 3, a horizontal section, showing the blind as thrown back, and its hook-fastening as engaged withlthe staple in the outside wall.

A represents the window-frame in part; B, the lower sash; and C, a hinged outside blind, provided with an ordinary spring double-hook fastening, D, the lips or noses b c of which en-v gage, respectively, with a staple, d in the window-frame or staple e in the outsidewall E, accordingly as said blind is closed orthrown open.

Pivoted to the inner end of the hook-fastening D is a iiat locking-bar, G, of a suitable length, so that when straightened out in line with the hook, after the blind C has been closed and fastened by the hooks engagement with the staple d, said bar, which rests on the window-frame, is clamped between the latter and the bottom of the lower sash B as said sash is loweredor closed, and is made to engage with said sash to lock the blind inits closed position. Thus the free or swinging end of said -bar is constructed with a turned-up lip, f, which, when the sash B is lowered, enters a cavity in the bottom thereof, as shown in Fig. 1. Said lip is doubled or bent over, thereby giving it a hollow or inverted U form, which not only adds to its strength, but provides forits engagementwith astaple, g, in the window-frame,

to lock the blind whenv the latter'is closed and the lower sash is raised, as shown in Fig. 2.

The engagement off/the locking-bar with the lower sash when the latter is closed insures a iirmer and more secure lock of it than does a mere engagement of it with the staple or pin in the window frame or sill, This locking-bar G also serves as a handle by which to manipulate the hook-fastenin g D to release the latters engagement with its staples, and is pivoted to the inner end of the hook or fasten'- ing D to facilitate such use of it, and to provide for its being closed against or into proximity with the blind when the latter is thrownback and its hook engages with the staple c in the outer wall, as shown in Fig. 3. Said lockingbar G may either be permanently pivoted to the double hookD, and form one of the elements of the fastening as exposed for sale or put upon the market, or it may be separately and afterward applied; and maybereadily and very conveniently attached to those hookfast enings now in use, which have a finger-hole or eye, h, in their inner ends, bymeans of onefor more flexible clamps or clips, ,passed through a slot in the bar G, through the eye I1l in the hook, and through a slotlin a backorlnnder washer k, and the entering ends of the clamp or clamps afterward bentover or down to secure such` pivoted union of the locking-bar with the hook.

The locking-bar G, when united with the eye h 0f the hook D, by one or more iiexible clamps or clips, z, and Washers k, @S llereigbog fone described, need not necessarily Vwith a turned-up or portion f at its locking end, but may be otherl doubled and turned-over Wise constructed to engage with vthe staple or projection on the Window sill or frameand,

with the lower sash., Vor either.

I claiml. The pivoted locking-bar G, having itsg turned-up portion or lip f doubled or turned over to provide for its engagement either? I' Witnesses:

l2, The combination, with the hook D, having an eye, h, of' the locking-bar G and one or more flexible clamps or clips, i, and washer k, essentialy as specied.
